Question 112: Geography

Which of the following weather conditions is indicated by a sudden fall in barometer reading?

aStormy weather
bCalm weather
cCold and dry weather
dHot and sunny weather

AnswerThe answer is (a).

A sudden fall in the barometer means falling air pressure, which signals the approach of a low-pressure system with cloud, rain and wind, so stormy weather is expected. A steady high or rising barometer means fair, dry weather. Remember: falling barometer, storm; rising barometer, fair weather.

Why each option is right or wrong
  • (a) Right: a falling barometer signals a storm.
  • (b) Calm weather goes with steady or rising pressure.
  • (c) Cold and dry weather goes with high pressure.
  • (d) Hot and sunny weather goes with high pressure.
